Because jumping off a mountain with just a pair of thin fabric wings underneath your arms isn't already dangerous enough, professional wingsuit flyers Fred Fugen and Vince Reffet decided to do that and then try and land inside an airborne plane, using a side door that was just a couple of metres from the aircraft's spinning propeller.[/size]The pair, who call themselves the Soul Flyers, practised the stunt over 100 times before strapping cameras everywhere to capture the action and leaping off the Jungfrau mountain in Switzerland. But next time we recommend just meeting the pilot at the airport before takeoff like the rest of us do.[/color]
